When Steve Jobs announced his resignation from Apple on Wednesday, it didn't just bring an end to his long reign as CEO of the company he co-founded. It also closed the book on one of the greatest legacies of innovation the technology industry has ever witnessed.
Jobs isn't just a savvy businessman, he's a visionary who made it his mission to humanize personal computing, rewriting the rules of user experience design, hardware design and software design. His actions reverberated across industry lines: he shook up the music business, dragged the wireless carriers into the boxing ring, changed the way software is sold, and forever altered the language of computer interfaces. Along the way, he built Apple up into one of the most valuable corporations in the world.
